.To all whom it may concern:

' its edge inward and the other by slitting the sole diagonally from itsflesh side outward or toward the edge. double lip is possible in aninsole which is relatively thick, but where the stock is thin or of lowgrade material a single lip only has been employed, such .lip beingusually formed by slitting the insole from its edge inward, all as wellknown by those skilled in the art. In turning the channel lip of suchsingle lip structure, a tool has been employed acting against the lip ina direction from the edge toward the center of the sole. Since the stockis usually thin and of low grade,

' it has been found necessary in practice,heretofore, to reinforce theinsole by means of canvas or the like cemented to the surface of thesole and covering both the inner and outer surfaces of the channel lip.Such application of the canvas to both surfaces of the channel lip isattended with muchdifliculty. The present invention, however, aims toovercome the necessity for covering both the inner and'outer faces ofthe channel lip with a reinforcing material, its object being to providea machine for turning a single channel lip upward and outward or towardthe sole edge, and providing means in connection therewith for consol1-dating the material of the; insole along the base of the channel, 11p,such consolidation of the material strengthening the sole outside andadjacent the base of the channel lip where the usual fasteningmeanspenetrates.

The objects and eneral purposes of the resent invention Wlll be betterunderstood rom the following description taken in connection with theaccompanying drawings, which show one of the various forms orembodiments of the invention.

' Figure. l isma side elevation-of a machine Such formation of embodyingthe elements of the present invention, parts being broken away and onlyso much of the machine being shown as necessary to a correctunderstanding of the invention. Fig. 2 is a front elevation of the partsof the machine head which act directly upon the sole, the remainingelements being omitted as unnecessary. Fig. 3 is a sectional detail onthe line 00-4 Fig. 2, showing a somewhat exaggerated form of insolebeing treated.

- The base A and head frame B may be of any usual or desiredconstruction, the said head being provided with a suitable bearing-1,for a shaft 2, driven from the worm-shaft 3 through a train ofmechanism comprising a worm 4, and connecting gearing 5 and 6 of ,7suitable character. 7

Mounted in a sliding frame 7 is a shaftfi,

to which is suitably secured the feed wheel Y 9 preferably having abroad support-in face, as shown, the said shaft. 8 being al" voperatively connected to the drive shaft 2 by suitable means,-such asthe Oldham clutch 10, which, while transmitting a posithe drive to theshaft 8 and feed wheel 9, readily permits said shaft 8 and feed wheel 9to be raised or lowered by means of the slid ing frame 7 as will beclearly understood by those skilled in the art without detaildescription, the details of said clutch forming no part of the presentinvention.

' Secured to the sliding frame 7 is a treadle rod 11, passing through abracket 12, and between saidbracket and tl1e 'slide ,7 said rod issurrounded by a coiled s ring 13 normally acting to raise said sli eagainst an adjustable stop 14 and bring the feed wheel and passing overpulleys 22 securedv to the worm shaft 3,, drives both the tool shaft 17and the worm shaft 3. It islsometimes desirable, though not alwaysnecessary, to employ a channel guide 23 td extend into the channel24: inthe insole-+25 and below the end of the lip turningtool 18, Fig. 3.

When used, this'guide 23 is preferably prolo vided with a recessedportion 26 into which 'the' lower end of the lip turning tool 13m?"raises/it for the action of t e lip turning tool 18. The guide 23 ispreferab secured by screws 28, 28 to thebearing 16 ofthe tool shaft andis bent as shown to place its end 26 beneath the end of the tool.

Adjustably mounted on the machinehead frame B is an arm 29, the outerportion of which is upturned somewhat and carries an edge'consolidatingmeans, herein shown as the consolidating wheel 30. The peripheral.portion of this consolidatingwheel is constructed and arranged to bearupon the edge portion of the insole adjacent the base of the channel lip31, Fig. 3, so that as the sole is fed through the machine and thesinglechannel lip is turned upward and out ward thereby tending to thicken thematerial -at-or adjacent the channel lip, the con-" solidating wheel 30coacts toreducethe tendency to thicken at the part stated and toconsolidate the material. This consolidation of theinsole takes placesubstantially at the line where the fasteners are to. ass and not onlystrengthens the materia by such consolidation but reduces its thickness,tending to forcetheupper surface at the base of and outsidel the-lip tothe level of the surface of the reinforcing material when placed in thechannel. l i

From the construction thus far described, it will be noted by thoseskilled inthe art that by reason of the singl'elip turning tool 18 an,its dis osition in the channel of the lip which is ormed by slittingthe insole diagonally toward the edge, the outer edge portion of theinsole adjacent the base of the lip may be acted. upon by aconsolidating device and the jinaterial strengthened by suchconsolidation which takes place simultaneously with the lip turningaction, without cutting awaythe material of the insole at such part andwhile maintaining the skin surface.

It has been found that an insole havin a channel lip formed by adiagonal'incislon towardthe edge and acted upon by the lip turning tooland consolidating wheel 30,

will feed readily. and quickly through the path of its treatment owingto the rotary character of the elements acting uponit, but at sharturns, as at the toe on instep, the rapid eed and change of direction ofthe:

sole isliable to cause it' to swingtoo far so that the tool may leavethe channel. To ob viate this, a stop 32 is provided somedistance-beyond and at the feed or. entrance side oi the machineale-indicated in Fig. 2.. This stop, preferably, is mounted'on the headB by means of the set screws 33, which pass through slots in the stoparm, by means of which a may be adjusted, Thus a will. i

be" clear thatthe lip turning tool 18. acts .on the channel surface ofthe lip, turning the lip upward and towardt-he sole edge, and' that theconsolidating wheel-30 acts upon the sole at and adjacent the outer baseportion ofthe channel. lip, said tool .and'consolidating wheel beingadjustable towardandfrom each other preferably by the set screw 34acting on the shank of the arm 29 carrying the consolidating wheel 30.The tool 18 e and consolidatin wheel 30 having received the'channel lipetween them by first depressing thefeed Wheel 9, as will be obvious,maintains. the lip in this. position during the treatment of the entirelip, so that a guide device to act upon the sole edge may be dispensedwith.

The action'of the consolidating wheel 30 in no sense sets the lip 31,because it does not 7.

act as an anvil upon theout-er surface of the lip, and consequently.the. lip-turning tool -18,can have no hammering action in setting" theunsupported material ofthe lip; the said consolidating wheel acting as'hereinbefore described to consolidate, strengthen, and depress thesurface of the edge portion of the sole outside of. and adjacent to thebase of the channel-lip,all as willbe readily understood by thoseskilled'in the art. Obviously, changes maybe made in the] form,character, and relation of the parts within the scope of the invention,and char-- acterizing; features of which are set forth in the claims bythe intentionaluse of generic terms and expressions inclusive of variousmodifications.
